Review on USB C to HDMI Adapter with Charging, CableCreation 3-in-1 Type C to HDMI, USB 3.0, USB C Power Port - Thunderbolt 3 Compatible for MacBook Pro 2019 2018, iPad Pro 2019, Surface Book 2, XPS 13 by Tony Dago

My use case for this is a USB-C dock for my Dell Latitude 5490. Here's what I've tested so far: 4K HDMI works with my laptop's Desktop Display Extension ( I haven't tried video streaming or movie playback). However, there was an occasional disconnect that I had to disconnect and reconnect to get the HDMI video back. - The Ethernet LAN is working. - USB A (connection to monitor hub). - USB-A works. - USB-C power adapter works (delivers enough power so the laptop doesn't complain). Issue: - Buzzing noise when connecting USB-C power adapter. I have to be careful and not leave it unattended when plugged in. I'm afraid it could start a fire.
